Abstract
A method for the manufacture of a light-emitting diode (LED) chip, the method comprising providing a first substrate; forming an LED structure on the first substrate, wherein the LED structure has a first surface adjacent the first substrate and a second surface opposite the first substrate; applying a second substrate on the second surface of the LED structure; and selectively etching the first substrate from the LED structure to form one or more walls extending from the first surface of the LED structure.
